We have a 2012 LT, purchased from Hertz in June with about 53k miles on it, now has about 62k. Long story short, we’ve had various warning lights, etc. go off, had a bit of fluctuation at idle, then lately started to stall when sometimes in idle, and finally the battery was dead when going to start it a couple mornings ago. As for the long version:

A couple months ago, the check engine light went on. Noticed some very slight RPM fluctuations at idle. Took it to AutoZone to have the code read, came up with something similar to my truck related to the MAF sensor…bought some cleaner, but didn’t really do much more checking into it. A couple days later, we had the coolant light go off. It stopped blowing hot air, and eventually started to overheat. We put some DexCool in, brought it to a shop who basically guessed that it had a bad thermostat. They also said that about eight codes came up. Ordered the part, and while waiting, started driving it a little and it never overheated again, so the part went back.

Started noticing that the fluctuations at idle were getting a little more pronounced…nothing as severe as what I’ve seen in some YouTube videos, but enough where we were just a tad concerned that it would stall after one of them. Then had the TPMS light go off…but after checking, nothing was wrong with the air pressure. Went along like this for a couple weeks, then other random notifications would come on, like the power steering and StabiliTrak lights. Then the radio would start cutting out and the headlights would flicker at the same time while driving on a few occasions.

Then about a week ago, went on a couple-hour cruise at night, with the fluctuations at idle getting a little wilder. Radio cut out a couple times on this drive. When we pulled up at home and put it in park, the car died. Happened again when parking after a normal half-hour or so drive. A couple days later, died at idle while waiting at a red light. And finally, it was completely dead when going to start it a couple days ago.

Do these symptoms sound the same or similar for anyone? Thanks!

There is a service bulletin & extended warranty coverage (special coverage 14311) out for a faulty negative battery cable until 120,000 miles.

I believe this is what's going on with your car. Ask the dealer to look up the extended warranty coverage & evaluate your car. It sounds unsafe to drive in this condition.

jblackburn, thanks so much. If it might not be a matter of the battery being drained (or is it?), is it no use trying to jump it? Would I just have to have it towed there?

What's the battery voltage on the dash say?

You could try jumping it if low, but it might be better just to take it into the dealer as-is and let them have a look at it in its current state so they don't give you any kind of run-around.

Ok, so the car was completely dead, wouldn't crank/click/anything. I had a guy come to tow it to the dealer...he said it was likely just a bad battery, even though I explained to him the symptoms that pretty much matched up with the special coverage (this one: http://www.cruzetalk.com/forum/25-s...al-coverage-14311-negative-battery-cable.html).

Ended up hooking up the jumper cables, and lo and behold, it started. That said, would you still bring it into the dealer? I was going to just take it to AutoZone to have the battery tested and probably buy another...but at that point, would I just be delaying the inevitable if it indeed is the terminal that needs to be replaced?

Jump it and have the battery tested as a first step. Entirely possible it's a bad battery, but you may have both issues.

Every time I go to the dealer it's at least a several hour wait, so this will at least save you some time if it is indeed just a bad battery. I have had terrible luck with the AC Delco batteries in my Cruze.

Take your time first of all .. we know you have a bad battery up to this point so it would be advisable to have that checked out ..

A trip to the Dealer should be in your plans also to have those cables checked out .

Will do, thanks again.

brian, hope you're liking Elmhurst, I've spent quite a bit of time there (also hope you're not often stuck in that traffic on 83 going south around North Ave. or so). I definitely love the weather, but have a fiancee who's nuts and misses the snow, so who knows where we'll end up.

Hopefully this will be resolved soon and I can start diving into the board for pleasure and start reaffirming again that this car has been the best auto decision we've made!

Here's my take: It sure sounds like you have a bad battery to me. But I'd have it tested since a bad cable can imitate a bad battery.

And it wouldn't surprise me but what a bad battery can imitate a bad cable. Take care of that "dead" problem and the others just might go away.

Makes sense...appointment scheduled for tomorrow morning at the dealer...free battery test, and if they find something wrong with the cable, no diagnostic fee, so nothing lost but a couple hours.

If they find a bad battery, he gets to buy a real battery with warranty at Autozone PepBoys or wherever.

You are in VA, you are conditioned from waiting in traffic to get to the dealership. I remember having 300 miles on a car and the a/c failed. No loaners no taxi home just 6 hours of trying to find someone with the part. That's when I found out you have better sales in Alexandria but better service in Arlington.

Hopefully it's just the cable. Does Hertz give you a maintenance history of the cars when you buy them or did you get this from a dealership and on inspection you found the Hertz oil change sticker on the door or under the hood?

Bought it right off the Hertz lot...unfortunately, no maintenance history was provided.

Big difference between a no start and a no crank. Had a no crank condition in my 2012 around three months ago, but due to a battery with a high self discharge rate. Still had a couple of months of bumper to bumper warranty left, but took me three dealers to replace it under warranty.

But someone moved the clock forward without my permission, so now I am struck with it, if this one goes, will have to buy a new one with my own money. When I first purchased this thing, noted that from the factory that all the battery terminals were dry. Used a battery terminal cleaner and silicone grease on everything to prevent what they call oxidation. So was good for the first 34 months.

This last time, noted the batter clamp bolts were crap, cheap cold rolled bolts and the terminal nuts couldn't even thighten them. So I replaced those with grade 8 1/4"-20 one inch long bolts that fit perfectly. Ha, to make it look stock, tapped the nuts also to the same thread size, nice and tight now.

04 Cavalier battery with a Delco name on it was still good after 8 years, but did a capacity test on it, and replaced it before giving this car to my daughter. Cruze battery also has a Delco name on it, but only God knows who made it. Delco is just a name now.

This new Delco battery replaced by the dealer only had a two month warranty left on it. Those two months went by awfully quick.

With a fully charged battery, as told by a maintenance type charger that tapers off to zero amps, the rest is a no brainer.

Just switch the headlamps on, blower motor and place the positive lead of a voltmeter on the terminal of the battery. Not the cable, but the actual battery terminal.

The negative lead on the engine block. If you read greater than 0.1 volts, you have battery connection problems. Same with the positive battery terminal, but have to go to one of the hot fuses in the underhood fuse box.

Well, the Cruze is at the dealer as of yesterday morning - got a call back from the service advisor saying that it WAS the negative battery cable and they had to order the part, so they'd need it overnight until today. The nice thing is that they also said that if the battery was bad, that special coverage would cover that as well. Just in case, I had bought one from AutoZone and stuck it in the trunk before I dropped it off, so that'll be nice to return.

The only disappointing thing to hear from the advisor was that she said that, even though I called and initially brought up the symptoms and the special coverage, she didn't want to put any of that on the initial filing and instead just start with saying I brought it in for a battery check. She said that even though the special coverages are able to be seen by the public, GM more often than not denies the claim if it's mentioned from the outset. Wasn't too pleased to hear that...but glad she was honest with me.
